DYEING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 535,005, dated March 5, 1895.

Application filed March 7, 1894.

To all whom it may concern:

Be it known that I, JOHN G. HASLAM, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Dyeing Apparatus, of which the following is a specification.

My invention relates to dyeing apparatus and consists of certain improvements which are fully set forth in the following specification and are shown in the accompanying drawings.

My invention is particularly adapted for dyeing yarn in the skein, and relates partly to improvements upon the apparatus disclosed in my Letters Patent No. 505,984., dated October 3, 1893.

A part of my improvements relate to the yarn carrying frame, whereby the efficiency and capacity of the machine may be increased.

In addition to the usual upper and lower sets of yarn sticks I employ an additional or intermediate set of sticks between the upper and lower sticks, with suitable supports therefor, by means of which two sets of skeins may be simultaneously dyed in the machine. By providing the sets of yarn stick supports with capacity of relative adjustment, the sets of sticks may be adjusted to suit sets of skeius of different sizes, so that large and small 0 skeins may be dyed simultaneously.

My invention also embraces improvements in the construction and arrangement of the lifting devices for raising and lowering the yarn frame with reference to the vat, and also 5 other improvements in construction and combinations of parts which are more fully set forth hereinafter.

Another part of my invention relates to the employment of an automatic valve device for controlling the supply of steam to the vat,

whereby, whenever the dye liquor is in danger of boiling over, the valve is automatically closed and the steam supply shut off, until the excessive ebullition has subsided.

I shall now refer to the accompanying drawings for the purpose of particularly describing my improvements.

A is the dye vat.

B is the yarn frame which is preferably of the general construction shown,consisting of the uprights B, the end cross pieces B B and B B connecting the uprights at the top and bottom, the longitudinal side pieces B B, at the bottom and the central longitudinal cross piece 0 at the top. The lower cross pieces B B may be used as the supports for the lower set of yarn sticks.

D, D, are the supports for the upper yarn sticks and are vertically adjustable upon the So uprights B, B, by means of the upright threaded rods D, D, extending through the ends of the cross piece 0, and the adjusting nuts D upon the threaded ends of the rods.

E are the upper yarn sticks carried by the frames D, D, and F are the loweryarn sticks carried by the frames B B The yarn frame is supported by the cross bar 0 in a frame K within which the bar C may reciprocate when the frame B is moved up and down in the liquor, so that it is not necessary to detach the yarn frame from the supporting frame while it is being reciprocated in the liquor.

To raise the yarn frame from the vat and to lower it therein suitable lifting devices connected with the supporting frame K are employed. These lifting devices are preferably operated by a hydraulic, air, gas or steam lift G.

The yarn frame is reciprocated in the liquor by means of rocking levers M having notched ends a which engage trunnions b on the end of the yarn frame. The levers which are pivoted to the vat as at 0, are operated by eccentrics O and eccentric rods 0 So far as I have described the apparatus it is substantially the same as the apparatus shown in my Letters Patent No. 505,984, heretofore referred to, to which reference may be made for greater particularity.

A part of my present improvements relate particularly to the construction of the yarn frame. To enable a single yarn frame to be employed for the purpose of simultaneously dyeing two sets of skeins, I employ an additional pair of yarn stick supports II located between the upper supports D and the lower supports 13 These additional orintermediate frames H may be made adjustable upon the uprights B, as by the upright rods H, H, extending up through the cross pieces B or guides 19 thereon, and carrying adjustable nuts H on their threaded ends.

I are the yarn sticks carried by the frames H, H. The yarn frame thus contains at each end three supporting frames for the yarn sticks located one above the other and capable of adjustment to vary their relative distances apart.

One set of skeins may be supported by the upper sticks E, and the intermediate sticks I, and a second set by the sticksI and thelower sticks F. The intermediate frames H, H, are preferably provided with two sets of supports or holes 2' to receive two sets of sticks I, so that there may be a separate row of sticks I for each of the upper and lower sets of sticks E and F. This, however, is not necessary to the invention, as the intermediate sticks I may all be arranged in one row if desired.

While I have shown the lower supports 13 stationary and the upper and intermediate supports D and H adjustable, it is apparent that this arrangement may be varied, and all of the supports may be adjustable or either the upper or intermediate supports may be made stationary, or two of the supports may be made stationary and one adjustable. I prefer the construction shown, however, as it enables the adjustment of the yarn sticks to be made from the top of the frame and without raising the frame from the vat, and this is particularly desirable when the skeins are to be supported loosely upon the sticks so that they may rise and fall upon the sticks during the reciprocations of the frame.

I prefer to arrange the pairs of sticks between which any skein is supported out of a direct vertical line, as is shown in Figs. 8 and 0, so that the skein will receive a more or less inclined position. This will cause the dye liquor to act more or less laterally upon the skein, and thereby to open the skein at the 'middle and permeate the fibers more evenly and quickly. For this purpose the supports in the two frames should be arranged out of a vertical line as shown. 1

The upright B may be provided with slots or grooves b to form guideways for the ends of the adjustable frames, which may be provided with tenons h fitting the slots.

In Figs. 2 and 5 is shown my preferred construction for uniting together the pieces 13', B B of the yarn frame. The ends of the pieces B and B are lap jointed and the bolt B is passed directly through the joint and into the end of the piece B whereitis secured by a nut b let into a recess.

In my former patent, No. 505,984, the lifting cylinder G is shown suspended from a movable carriage on a fixed independent rail above the vat. In the present improvement the apparatus is supported from the vat by means of an overhanging frame, which permits the yarn frame to be lifted from the vat and moved laterally away from it. The yarn frame may then be lowered to the floor outside of the vat.

In the construction shown in Figs. 1 and 10 J is a frame extending above the vat A and having overhanging arms J which extend materially beyond the front of the vat. L, L are guides or idlers journaled in the upper part of the frame J at the front and rear. N is a rail carried by cables or chains P, P, which pass up over the idlers L, L, respectively and connect with the piston rod R of the lifting cylinders G which may be fastened directly to the vat A or to the frame J. The operation of the lifting cylinder Gr will raise and lower the rail N. The frame K is provided with a trolley K which runs upon the rail N. The rail N is of sufficient length to extend laterally beyond the vat A as shown. When the rail N is raised by the lift G, the yarn frame B is lifted with it from the vat. When the rail is properly elevated, as indicated in dotted lines in Fig.1, the yarn frame may be moved upon the rail N until it reaches a position beyond the vat. The rail N may then be lowered permitting the yarn frame to descend to the floor. To raise the yarn frame from the floor and introduce it into the vat these operations are reversed. To steady the rail N when it has been elevated, the frame J may be provided with seats j, into which the rail is received when it reaches its highest position.

In the construction shown in Fig. 3 instead of employing the movable rail N, the cylinder G is carried by a movable carriage N which may be moved laterally upon the top of the frame J. In this case the cylinder must be connected with its source of power by a jointed or flexible pipe G.

In Figs. 4 and 6 are shown the valve devices for automatically controlling the supply of steam to the dye vat. When steam is supplied excessively to the vat, the dye liquor is liable to boil over. It has been usual to provide the vat with an overflow pipe or level.

outlet to permit that liquor to escape which boils above the normal level. This is objectionable because it does not affect the steam supply, although that is the cause of the difficulty, and also because it results in waste and materially reduces the quantity of dye liquor in the vat. My improvements are designed to obviate these objections by providing the steam pipe with a valve device which shall automatically shut off the steam supply whenever the liquor boils above the proper For this purpose I employ a valve in the steam supply pipe connected with an expansible pipe or piece subjected to the liquor.

Q is the usual steam pipe entering the vat This pipe is provided with a valve case Q, in which is located a valve 8 adapted te a seat q in the case. The stem 5 0f the valve extends through the case Q and is carried by the closed end of an overflow pipe S, which leads from the vat at the usual overflow level. The particular construction of the valve 8 is immaterial. I have shown it as a gate valve adapted to a seat q in the case Q. The overflow pipe S may be provided with an outlet S. Whenever the dye liquor boils above the level of the overflow outlet, the boiling liquor will pass into the pipe S and heating it will cause it to expand. This expansion of the pipe S will move the valves carried by it into the seat q, and will thus shut off the steam supply to the vat through the pipe Q. Such liquor as passes into the pipe S may escape through the outlet S. The quantity of liquor thus wasted will, however, be very little, compared with the amount that is lost with the ordinary overflow.

When the temperature of the liquor becomes reduced by the shutting off of the steam supply, and ceases to boil into the pipeS, that pipe becomes cooled and contracts,thus withdrawing the valve 3 from the seat (1 and opening the steam supply through the pipe Q. The pipe S should of course be constructed of metal having a high coefficient of expansibility.

To insure the greatest expansion of the pipe S taking place in the direction toward the pipe Q the rear end of the pipe S may be held to the case Q by a cross piece T and rods as shown in Fig. 4. By'this means the rear end of the pipe S will be held in a more or less fixed relation with reference to the valve seat q, while the front end which carries the valve 8, will be free to expand and move forward. The amount of movement for the opening and closing of the valve need be very slight.

Such minor details of construction as I have shown for the purpose of illustrating and explaining my invention may be varied as may be desired and are not to be taken as limitations of the invention.
